First report and damage description of Calodesma collaris (Drury, 1782) (Lepidoptera: Erebidae) caterpillars on Aechmea winkleri Reitz, 1975 (Bromeliaceae).
We report for the first time the occurrence of Calodesma collaris (Drury, 1782) (Lepidoptera: Erebidae) caterpillars on Aechmea winkleri Reitz, 1975 (Bromeliaceae) and describe the damage it causes on these plants. The consumption of leaf tissue, accumulation of excrements and inhibition of inflorescence emission caused by larvae of C. collariscan result in plants of A. winkleri that are not suitable for ornamental or landscaping purposes
Lupus vulgaris reported in 2 cases
Department of Dermatovenerology, State University of Medicine and Pharmacy "Nicolae Testemitanu", Chișinău, Republic of Moldova, Congresul consacrat aniversării a 75-a de la fondarea Universității de Stat de Medicină și Farmacie „Nicolae Testemițanu” din Republica Moldova, Ziua internațională a științei pentru pace și dezvoltareIntroduction:
Cutaneous tuberculosis is a group of polymorphous and
varied manifestations of the skin and mucous membranes,
produced by infection with some species of Mycobacterium
tuberculosis complex. The specific primary lesion is the
lupoma, sometimes evolving into mutilating forms.
Purpose:
Lupus vulgaris particularities reported in two clinical cases.
Material and methods:
A 68-year-old female, presented for multiple infiltrative,
prominent erythematous plaques and placards with
various diameter, well contoured by a violaceus halo, with
irregular contour on the trunk. A 6-year-old boy presented
for brownish-red, soft papules with smooth surface on the
face and trunk. The lesions appeared 3 years ago; and 6
months ago after a minor trauma injury, the lesions have
spread.
Results:
Chest X-ray didn’t reveal any abnormalities. During
dermascopy the sign of “apple jelly” was found positive.
Histopathological exam found caseous necrosis,
tuberculoid granulomas composed of epithelioid cells and
Langhans giant cells, surrounded by mononuclear and a
dense lymphocyte infiltrate localized in the dermis.
Mantoux probe was 17 mm in diameter. Clinical
examination sustained by the histopathological exam and
Mantoux probe inferred the diagnosis of lupus vulgaris
(tuberculosis).
Conclusions:
The particularities of the presented cases with distinct
clinical signs, the histopathological presence of
granulomatous inflammation with specific cellular
appearance, the hyperergic Mantoux test and the lack of
characteristic pulmonary changes represent a casuistic
interest of lupus vulgaris

First record of Dysmicoccus boninsis Kuwana, 1909 (Hemiptera: Pseudococcidae) on sugarcane in the state of Rio Grande do Sul.
Among the sap-sucking insects that infest sugarcane [Saccharum spp. (Poaceae)] around the world, scale insects (Hemiptera: Coccomorpha) stand out with 103 recorded species. Most of them are frequently regarded as secondary or occasional pests (Garcia Morales et al., 2016). In Brazil, eighteen species of scale insects have already been reported on sugarcane. Of these, Aclerda takahashii (Kuwana, 1932) (Aclerdidae), Margarodes sp., (Margarodidae) and Saccharicoccus sacchari (Cockerell, 1895) (Pseudococcidae) are known to the state of Rio Grande do Sul (Garcia Morales et al., 2016; Borges Filho et al., 2019; Monteiro et al., 2019).First online
